i put a rearend from an S10 4wd under my '50 coupe. the 4wd rear is wider thn the 2wd which would be too narrow. the 4wd rear is 3/4" more narrow than the original. all that's needed is new spring pads. many were in S10 blazers with towing packages which means posi, & a broad range of gear ratios is available. the boneyards around here are full of them & they're reasonably priced. these 7.5" ring gear axles were used in f-bodies & many other gm applications for many years. while it is not what you'd want in your drag car with the big block v-thing, it should suit our inline cars just fine.
